It would appear that every optical has at the least purchased one optical centering device (at some point in time) in an effort to better fit glasses and impress patients with their futuristic technology. But as it would seem these devices haven’t caught on- and still further, manual measurements seem to be the standard practice. It could be that these instruments cost way too much; when Essilor gives their Visioffice device away for free to top performing locations it also makes us question why we should pay anything for these devices. It may also be that the data they produce isn’t much more efficient than manual measurements, or that actually performing scans is too time consuming. We tend to agree that optical measuring devices have dwindling appeal despite the technological stunt that is appealing to patients with shiny new tech. As a side note- it also feels as if it makes the optician less of a lens master and more of a sales person- operating a robot to seal the deal. Although we do find the RV Terminal to be quite accurate- with fewer mistakes than your veteran technician that’s currently out at lunch.
OUR TAKE: Impress patients with shiny technology that struggles to replace the optician.
- Patented laser speckle target system allows patient’s eyes to relax for accurate distance PD measurement.
- Precision digital camera captures both frontal and profile images of patient wearing their chosen frame.
- Computerized measurement system processes images automatically, measuring monocular interpupillary distances, fitting heights, pantoscopic angle, vertex distance, and frame wrap to an accuracy of 0.1 mm.
- Automatically takes vertex distance, lens tilt and frame wrap measurements for the patient’s chosen frame.
- Allows advanced progressive lens customization using free-form technology.
- Displays the images of the patient in their chosen frame for review with dispenser.
- Allows patients with strong prescriptions to see how frames will look when worn.
- Enhanced mirror allows dispenser to add tints, photochromics and AR to images, so patients can see how lens enhancements look and function.
The RV Terminal does require an external monitor (included) in order to display results and navigate the measurement user interface. The RV Terminal’s software is however included within the device and does not require an external computer to operate.
The patient is required to wear a ‘Lens Blank Patient Measuring Module’ device that is identified by the device when a measurement is performed. The patient may also wear their existing or proposed eyewear.
